For a debug environment, I am using OpenOCD with a Wiggler-clone JTAG interface. The
following steps worked for me with a 20081028 OpenOCD snapshot.
GENERAL STEPS:
1. Check out OpenOCD
svn checkout svn://svn.berlios.de/openocd/trunk openocd
2. Build OpenOCD
Read the INSTALL file from the files you just downloaded. You probably just need
to run:
./bootstrap
Then configure OpenOCD using the configure script created by ./bootstrap.
./configure --enable-parport
Build OpenOCD with:
make
Install OpenOCD. Since we used the default configuration the code will be
installed at /usr/local/bin/openocd. Other files will be installed at
/usr/local/lib/openocd (configuration files, scripts, etc.) and /usr/local/share/info
(online documentation accessable via 'info openocd'). You need root priviledges
to do the following:
make install.
3. Setup
OpenOCD reads its configuration from the file openocd.cfg in the current directory
when started. You have two different options:
* Create a symbolic link named openocd.cfg to one of the configuration files in
/usr/local/lib/openocd, or
* Use a custom configuration file specified with the ‘-f <conf.file>’ command line
switch opeion when starting OpenOCD.
For the STR-P711, I have included bash scripts in the scripts sub-directory.
4. Running OpenOCD
Make sure the ARM7TDMI board is powered and the JTAG cable is connected
Run 'src/openocd -d' (might be required to be root) and check for any errors
reported. The '-d' option enables debugging info.
5. Telnet interface
telnet into port 4444 to get a command interface: 'telnet localhost 4444'
6. GDB
start arm-elf-gdb
type 'file <executable.elf>' to load the executable
type 'set debug remote 1' to enable tracing of gdb protocol (if required)
type 'target remote localhost:3333' to connect to the target
The same commands from the telnet interface can now be accessed through the
'monitor' command, e.g. 'monitor help'
